Tire sidewall



FIG. 1 is a perspective view of a tire sidewall according to my design;

FIG. 2 is a front view thereof;

FIG. 3 is a top view thereof;

FIG. 4 is a right side view thereof;

FIG. 5 is a rear view thereof;

FIG. 6 is a fragmentary enlarged view showing the details of the sidewall defined by cross-section by lines 6-6 and 6-6 in FIG. 2; and,

FIG. 7 is a section view taken along line 7-7 between 7-7 in FIG. 6.

The broken lines show unclaimed environment, and thus form no part of the claimed invention.
